工作流<输出>和<结束节点>使用api调用和chatsdk不显示

这两个节点的文本在bot预览与调试页面可以显示，调用api 或者是chatsdk直接对话流程就结束了，没有输出结束节点的文本。
另外输入节点和问答带选项的节点 在预览与调试页面可以正常显示输入，使用chatsdk不显示。

Start by reproducing the workflow in the bot preview/debug page, through the API, and through ChatSDK. Trace handling for output, end, input, and option-based question nodes, then verify that their text and inputs appear consistently in API and ChatSDK conversations.
